Description

Technical Field

[0001] The utility model relates to the technical field of loading machinery, in particular to a stacking mechanism for packing cases of a walking type loading machine. Background Art

[0002] When products leave the factory, they are often packed in packing cases. The packing cases are made of various materials, such as paper, wood, plastic, etc. The packing cases have the advantages of being convenient to use and transport, reliable and safe in packaging, and low in cost, so they are widely used in various industries. However, there are many drawbacks in the process of loading the packing cases onto vehicles.

[0003] For example, after the existing packing cases are sent into the freight car compartment by manual labor or a belt conveyor, they need to be manually carried down from the belt conveyor and arranged layer by layer in the compartment. When stacking at a relatively high position, ladders or forklifts are needed for stacking. Therefore, a lot of operators need to cooperate to stack the packing cases, which not only has low work efficiency, but also has a large labor intensity and wastes limited human resources. In addition, when stacking the packing cases in this way, it is easy to cause damage to the items inside the packing cases due to improper operation resulting in the packing cases being knocked or dropped during loading or transportation, thus causing unnecessary property losses.

[0004] Therefore, replacing manual loading operations with automated loading equipment has become a development trend in the logistics industry. The walking type loading machine is an automated equipment, which is provided with a conveying mechanism, a horizontal arranging mechanism and a stacking mechanism. The conveying mechanism conveys the packing cases to the horizontal arranging mechanism and then pushes them into a row, and then the whole row of packing cases is sent to the stacking mechanism to stack the whole row of packing cases into the freight car compartment in sequence. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a stacking mechanism for packing cases of a walking type loading machine, which is used to stack the row of packing cases sent by the horizontal arranging mechanism into the freight car compartment, so as to solve the drawbacks of manual loading and improve the loading efficiency.

[0025] Embodiment 1

[0026] As Figures 1 to 4 shown, a stacking mechanism for packing boxes of a walking type loading machine is arranged on the output side of packing boxes on the left side of the horizontal arrangement mechanism 2 of the walking type loading machine, and includes a frame 6, a rectangular stacking bottom plate 320 which can be vertically lifted and arranged on the left side of the frame 6, a rectangular stacking platform 304 arranged above the stacking bottom plate 320, a horizontal long strip-shaped flipping push board 302 arranged on the right side of the stacking platform 304, and a flipping box pushing unit arranged on the stacking bottom plate 320 for erecting the flipping push board 302 and then longitudinally moving along the upper surface of the stacking platform 304. The stacking bottom plate 320 and the stacking platform 304 are fixedly connected through a connecting vertical plate 332 arranged between the stacking bottom plate 320 and the stacking platform 304, and the stacking bottom plate 320 is horizontally arranged transversely.

[0027] The right side of the stacking bottom plate 320 is connected with a lifting unit. The lifting unit includes a lifting frame 305 arranged on the right side of the stacking bottom plate 320. The lifting frame 305 is vertically slidably connected with the frame 6 through a first vertical slide rail module 311. The track of the first vertical slide rail module 311 is fixedly connected with the left side of the frame 6, and the slider of the first vertical slide rail module 311 is fixedly connected with the right side of the lifting frame 305.

[0028] The stacking bottom plate 320 is vertically slidably connected to the lifting frame 305 through a second vertical slide rail module 333. The rail of the second vertical slide rail module 333 is fixedly connected to the left side of the lifting frame 305, and the slider of the second vertical slide rail module 333 is fixedly connected to the right side of the stacking bottom plate 320.

[0029] At the top of the frame 6, two longitudinal, symmetric and parallel channel rails 310 are fixedly connected to the right of the lifting frame 305. Both of the two channel rails 310 are made of C-shaped steel. A trolley 309 is arranged between the two channel rails 310. The wheels at both ends of the trolley 309 are respectively located in the grooves of the corresponding channel rails 310, so that the trolley can travel along the channel rails 310.

[0030] A first sprocket 308 is rotatably connected to the left side of the trolley 309. A second sprocket 315 is rotatably connected to the left end at the top of the frame 6. A third sprocket 312 is rotatably connected to the bottom of the lifting frame 305. A fourth sprocket 313 is rotatably connected to the top of the lifting frame 305. A chain 306 is connected to the frame 6. One end of the chain 306 is fixedly connected to a part of the frame 6 between the trolley 309 and the lifting frame 305, and the other end sequentially bypasses the first sprocket 308, the second sprocket 315, the third sprocket 312 and the fourth sprocket 313 and then is fixedly connected to the right side of the stacking bottom plate 320.

[0031] The first sprocket 308, the second sprocket 315, the third sprocket 312, the fourth sprocket 313 and the chain 306 form a chain drive unit, and two symmetrically arranged chain drive units are provided. A longitudinal lifting hydraulic cylinder 307 is arranged on the frame 6. The lifting hydraulic cylinder 307 is arranged between the two chain drive units. The two ends of the lifting hydraulic cylinder 307 are respectively hinged to the frame 6 and the trolley 309. The channel rails 310 are located below the pushing mechanism 2, so that the structure is more compact.

[0032] A horizontal strip plate 301 is further arranged on the right side of the flipping push plate 302. The strip plate 301 is fixedly connected to the top surface of the connecting vertical plate 332 and is used to fill the gap between the flipping push plate 302 and the horizontal row mechanism 2.

[0033] After the horizontal row mechanism 2 pushes the row of packaging boxes onto the stacking platform 304, when the lifting hydraulic cylinder 307 extends, driven by the chain 306, first the stacking bottom plate 320 rises. When the stacking bottom plate 320 rises to the top of the lifting frame 305, it drives the lifting frame 305 to rise under the action of the limit block at the top of the lifting frame 305 until the height of the packaging box stacking is reached. The flipping push box unit makes the flipping push plate 302 stand up and then pushes the whole row of packaging boxes on the stacking platform 304 to the left into the carriage.

[0034] Since after the stacking platform 304 rises, the stacking platform 304 first rises to the top of the lifting frame 305, and then the lifting frame 305 drives the stacking platform 304 to rise together. Therefore, the lifting frame 305 will not be higher than the top of the stacking platform 304. Thus, when stacking the packing boxes into the carriage, the lifting frame 305 will not hit the top of the freight car carriage. Therefore, the utility model can stack the packing boxes near the top of the carriage and can fill the carriage with packing boxes from bottom to top.

[0035] The utility model can replace manual labor to stack the packing boxes into the freight car carriage in sequence, improves the stacking efficiency, and is safe and reliable during stacking, and the phenomenon that the internal items are damaged due to the collision of the packing boxes will not occur.

[0036] A secondary platform bracket 314 is also fixedly connected to the right side of the stacking bottom plate 320, and the secondary platform bracket 314 is fixedly connected to the bottom surface of the secondary platform 205 of the horizontal row mechanism 2. When the stacking platform 304 rises with the lifting frame 305, it drives the secondary platform bracket 314 to rise together, thereby preventing the secondary platform 205 above the lifting frame 305 from affecting the rising of the lifting frame 305. The lifting frame 305 is arranged below the horizontal row mechanism 2, making the overall structure of the loading machine compact, occupying less space and being more flexible.

[0037] Embodiment 2

[0038] As Figures 3 to 6 shown, the difference between this embodiment and Embodiment 1 is that:

[0039] The flipping and pushing box unit includes a longitudinal pushing linear slide table 318 arranged longitudinally on the stacking bottom plate 320, a longitudinal flipping slide plate 323 fixedly connected to one side of the pushing linear slide table base 326 of the pushing linear slide table 318, and a flipping swing arm 325 with one end rotatably connected to the side of the pushing slider 322 of the pushing linear slide table 318 close to the flipping slide plate 323. The pushing linear slide table 318 is a screw linear slide table driven by a servo motor.

[0040] The flipping swing arm 325 is arranged longitudinally. The other end of the flipping swing arm 325 is close to the horizontal row mechanism 2 and is fixedly connected to the bottom surface of the flipping push plate 302. A longitudinal flipping chute 324 is provided inside the flipping slide plate 323. One end of the flipping chute 324 close to the horizontal row mechanism 2 extends downward so that the flipping chute 324 forms an L shape. A flipping sliding pin 328 is fixedly connected to the flipping swing arm 325, and the flipping sliding pin 328 is located inside the flipping chute 324. When the flipping push plate 302 is horizontal, the flipping sliding pin 328 is located at one end of the flipping chute 324 close to the horizontal row mechanism 2 and the flipping sliding pin 328 is lower than the rotation center of the flipping swing arm 325. When the pushing slider 322 of the pushing linear slide 318 moves longitudinally away from the horizontal row mechanism 2, the flipping sliding pin 328 first rises along the flipping chute 324, and then slides longitudinally away from the horizontal row mechanism 2 inside the flipping chute 324. During this process, one end of the flipping swing arm 325 close to the horizontal row mechanism 2 flips upward by 90 degrees, making the flipping push plate 302 stand up, and then moves longitudinally away from the flipping push plate 302.

[0041] Rectangular movable platforms 303 are provided on both sides of the stacking platform 304 along the transverse direction. The top surface of the movable platform 303 is flush with the stacking platform 304, and there are gaps between the movable platform 303 and the stacking platform 304. The movable platform 303 is fixedly connected to the base 326 of the pushing linear slide, and the base 326 of the pushing linear slide is slidably connected to the stacking bottom plate 320 transversely. A transverse driving unit for driving the base 326 of the pushing linear slide to slide transversely is provided on the stacking bottom plate 320.

[0042] There are four pushing linear slides 318. Correspondingly, the flipping swing arms 325 connected to the four pushing linear slides 318 are respectively arranged on both sides of the two movable platforms 303. When the flipping sliding pin 328 slides along the flipping chute 324 away from the horizontal row mechanism 2, the outer end of the flipping swing arm 325 flips upward and moves along the side surface of the movable platform 303.

[0043] In this embodiment, the two movable platforms 303 are driven to move transversely by the transverse driving unit, so as to adapt to the width of the carriage. When the horizontal row mechanism 2 pushes the packaging boxes onto the stacking platform 304 and the movable platform 303, the flipping push plate 302 is in a horizontal state, which facilitates the passing of the packaging boxes. The erection and box-pushing actions of the flipping push plate 302 can be achieved only by the action of the pushing linear slide 318, and the structure is simpler and the failure rate is lower.

[0044] Embodiment 3

[0045] As Figure 3 and Figure 4 shown, the difference between this embodiment and Embodiment 2 is that:

[0046] The horizontal driving unit includes a horizontal movement driving motor 331 with its output shaft facing upward, which is fixedly connected to the middle part of the upper surface of the stacking bottom plate 320. The horizontal movement driving motor 331 is a servo motor. Four pushing linear sliders 318 are symmetrically arranged in two groups on both sides of the horizontal movement driving motor 331, with two in each group. Two mutually parallel horizontal first horizontal slide rails 316 are fixedly connected between the two horizontal movement driving motors 331 in each group. A horizontal movement rotating arm 330 is provided on the output shaft of the horizontal movement driving motor 331. The outer ends of the horizontal movement rotating arms 330 are each provided with a horizontal second horizontal slide rail 319, one end of which is fixedly connected to the inner side of the pushing linear slider base 326 of the inner pushing linear slider 318.

[0047] The middle part of the horizontal movement rotating arm 330 is fixedly connected to the output shaft of the horizontal movement driving motor 331. Second horizontal sliders 327 are fixedly connected to the stacking bottom plate 320 below the second horizontal slide rail 319. The second horizontal slide rail 319 is slidably connected to the second horizontal slider 327. The other end of the second horizontal slide rail 319 is both rotationally and slidably connected to the outer end of the horizontal movement rotating arm 330.

[0048] One end of the second horizontal slide rail 319 close to the horizontal movement rotating arm 330 is fixedly connected with an intermediate connecting plate 321. A longitudinal chute is provided on the intermediate connecting plate 321. A cylindrical pin that can slide longitudinally therein is provided in the chute. The cylindrical pin is fixedly connected to the outer end of the horizontal movement rotating arm 330, thus realizing the rotational and sliding connection between the second horizontal slide rail 319 and the horizontal movement rotating arm 330.

[0049] In this embodiment, one horizontal movement driving motor 331 can drive two movable platforms 303, realizing the synchronous reverse movement of the two movable platforms 303. The structure is compact, simple and reliable.
